Sanitary and storm sewer systems are an integral part of an urban area. Waste treatment facilities are carefully designed for industrial, institutional, commercial, and population wastes. To ensure proper flow of waste and storm systems, pre-benched manhole bases allow smooth transition and flows at junctions, change of pipe sizes and lateral connections. The pre-benched manhole base consists of a section of monolithically poured manhole barrel with channeled concrete between the inverts of inlet/outlet pipes with a minimum slope of 25mm or 1". The channeled concrete is smooth finished and in most cases a gasketed opening is provided for the insertion of inlet/outlet pipes. The manhole base has a joint on the top to allow for riser sections to be placed to reach the installation invert. The pre-cast, pre-benched manhole base allows for a high quality and quick alternative to cast in place benching. Using pre-cast, pre-benched manhole bases minimize construction time in the field and ensures a quality, long term solution in building storm and sanitary sewer infrastructure. Most pre-benched manhole bases are custom built for the contractor where the angles between the inlet/outlet mains require specific layout. In some cases straight through, 45 or 90 degree configurations are available for standard pipe sizes of 100-200 mm.  2, record 1, English, - pre%2Dbenched%20manhole

Inlet and Interceptor/Distribution Chamber. The invert of the inlet pipe is above the static operating surface level of the separator to provide positive drainage of the inlet pipe. The inlet pipe is designed to conform to the flow capacity of the separator... Separation Chamber. In the McTighe separator, the separation chamber is designed to provide adequate volume for the coalesced oil droplets to reach the surface for effective separation. The separation chamber size increases in relation to the increasing wastewater volume requiring treatment... Outlet Chamber. The discharge pipe opening is located at the furthest point distant from the inlet at the most quiescent zone of the separator. The invert of the outlet pipe establishes the static surface level of the separator. The outlet pipe is designed to conform to the flow capacity of the separator.  1, record 2, English, - outlet%20chamber
